Method for selecting and connecting of interface supporting multimedia call service

An interface selection/production method capable of supplying high-capacity data through an access node at high speed is provided to supply the high-capacity data at high speed by receiving a service and connecting an optimum access node. A signal intensity measurement result of an access node which is adjacent to a terminal and a multimedia call connection request is received from a terminal which is a first multimedia call(S410). An optimum access node is selected by the received signal strength measurement result based on the radio resource database which is pre-stored in the second multimedia call connection(S430). The second multimedia message is delivered to the terminal through the access node. The tunnel formation request is delivered(S452). The resources are allocated to the preference base station.
